"Alte Burg" (old castle) – Headquarters of the Gestapo
No plaque commemorates the fact that the rooms of the former Alte Burg housed the Klagenfurt Gestapo branch office, after the original offices in the building of the Carinthian state government had soon become too small. Whereas the majority of the prisoners were quartered in the building of today's regional court prison (see below), this was the place were the civil servants who devoted their time to Bandenbekämpfung (fight against partisans), monitoring "political enemies", or the persecution of Jews resided. From here the subordinate Gestapo offices in Lienz, Spittal an der Drau, Dravograd (Unterdrauburg), Villach/Beljak and later also in smaller bases such as Ferlach/Borovlje were coordinated. Furthermore, the Gestapo had an extensive web of spies – often prisoners would be blackmailed into spying. Not least, the sheer power of the Gestapo arose from its right to perform arrests without limitation and the right to have Schutzhäftlinge (literally: prisoners in protective custody) sent off to a concentration camp. Forced labourers from Eastern Europe could even be sentenced to death and executed. The Gestapo played a decisive part in the national-socialist terror apparatus against Jews and Slovenians as well as "political enemies".Today the former offices of the Gestapo employees and the interrogation rooms are used by civil servants to administrate culture in Carinthia.
